IMPROVEMENT IN FLUID-METERS.A

Specilcaton forming part of Letters Patent No. 169.703., dated November 9, 1875; application tiled April 24, 1875.

iiuid; and it consists of a contrivance ot' the pipe so that the roller may travelon a level way all round, and an arrangement of the roller by which to connect the recording mechanism in a simple way.

Figure l is a section otmyimproved meter, taken on line .c x ot' Fig. 2. Fig. 2 is a plan view and Fifr. 3 is a section of Fin'. 2 on line Simlar letters of reference indicate correspondin g parts.

A-represents the circular tube, of flexible material7 in flat form, arranged on the flat and level bed B, with the inlet at C, and vthe outlet D overlapping the inlet, so that the rollerE will be carried beyond the inlet before it escapes from the inluence of the discharging t'luid, the inlet being so constructed by being made narrower or being fastened downto the bedplate under the discharge, and for a little distance beyond, that it does not rise as high by the fluid as the discharge does, so that the roller passes smoothly'and surely over the inlet and discharge, thus saving the necessity of making the bed and the circular tube spiral, as they have heretofore been made. The tube is made of three layers of flexible material, a, b, and d, the two upper ones, c and b, being cemented together at the outer and inner edgesf, and b being cemented at the middle of the under side to the bottom layer d., to secure it in position, and at the same time allow of the inflation of the tube by the Huid. The bottom layer forms a portion of the tube at the inlet c, and the rest of ment that the roller has only to be pivoted to4 a center stud, G, by a stem, H, with an 'eyein it, and this stem will serve for driving the recording mechanism by turning a wheel above by means ot' a crank-pin, J, extending down from the side ofthe wheel in front of the stems.

.An important advantage of the arrangement, whereby the roller travels on a level way, is, that two rollers may be used on one stem, the latter being extended on the opposite side of the pivot, one ot' which rollers will balance the other in case the machine does not stand quite level.

Having thus described my invention, l claim as new and desire to secure by Letters Patentl. The combination, with roller E, of flat flexible tube A and level bed B, having inlet C, as shown and described, for the purpose specified.

2. The roller7 connected to the center stud G by an eyevstem, H, arranged to turn the crank-pin of .recording apparatus, substantially as specitied.

3. The tube, constructed of three plies ot' flexible material, a, b, and d, and the inlet arranged between the .bottom and middle plies, substantially as specified.

4. The bottom piece ot' the tube, arranged to form the packing of the inclosing-case, and for attaching the flexible tube to thc bed.
